Abstract:
Objective:To review the imaging characteristics and evaluate the diagnostic value of Doppler echocardiography for congenitally malposition of septum primum(MSP).Methods:Images of Doppler echocardiography were retrospectirely rewiewed and compared with CTA, operative and necropsy findings in 8 cases with MSP in Xinhua Hospital, and Shanghai Children′s Medical Center, Shanghai Jiaotong University School of Medicine from January 2009 to October 2019.Results:MSP was characterized by the absent of superior limbic band of septum secundum and different degrees of the leftward deviation of septum primum, and the pulmonary veins which connected with the posterior wall of the anatomical left atrium incorporated intothe right atrium. The associated malformations included totally anomalous (7 cases) and partially anomalous (1 case) pulmonary venous drainage directly to the right atrium. Six of 8 cases were diagnosed correctly. In the remaining 2 cases, 1 case misdiagnosed as single atrium, and the other case misdiagnosed as cor triatriatum.Conclusions:MSP could be diagnosed accurately by Doppler echocardiography. This malformation should be distinguished from single atrium and cor triatriatum.
